The fixed angle conjecture for QAOA on regular MaxCut graphs
Jonathan Wurtz, Danylo Lykov
The quantum approximate optimization algorithm (QAOA) is a near-term combinatorial optimization algorithm suitable for noisy quantum devices. However, little is known about perform…
Classically optimal variational quantum algorithms
Jonathan Wurtz, Peter Love
Hybrid quantum-classical algorithms, such as variational quantum algorithms (VQA), are suitable for implementation on NISQ computers. In this Letter we expand an implicit step of V…
Emergent conservation laws and nonthermal states in the mixed-field Ising model
Jonathan Wurtz, Anatoli Polkovnikov
This paper presents a method of computing approximate conservation laws and eigenstates of integrability-broken models using the concept of adiabatic continuation. Given some Hamil…
Variational Schrieffer-Wolff Transformations for Quantum Many-Body Dynamics
Jonathan Wurtz, Pieter Claeys, Anatoli Polkovnikov
Building on recent results for adiabatic gauge potentials, we propose a variational approach for computing the generator of Schrieffer-Wolff transformations. These transformations…
Quantum Hydrodynamics in Spin Chains with Phase Space Methods
Jonathan Wurtz, Anatoli Polkovnikov
Connecting short time microscopic dynamics with long time hydrodynamics in strongly correlated quantum systems is one of the outstanding questions. In particular, it is very diffic…
Cluster Truncated Wigner Approximation in Strongly Interacting Systems
Jonathan Wurtz, Anatoli Polkovnikov, Dries Sels
We present a general method by which linear quantum Hamiltonian dynamics with exponentially many degrees of freedom is replaced by approximate classical nonlinear dynamics with the…
